Oval ring joint gasket is machined from solid metals in a variety of shapes.They are designed for high pressure, high temperature or highly corrosive applications.These basic shapes are used in pressures up to 10,000 psi. The dimensions are standardized and require specially grooved flanges.It is made of the most suitable material and shapes.
ZD-G1800 ring joint gasket oval type is also called RTJ oval type. It is mechanically made from integral metal include soft iron, SS304, SS316, carbon steel, SS321. It is mainly used in the joint part of high-temperature, high-pressure pipeline, tower, groove and heat exchanger, suitable for steam industry, petroleum industry and petrochemistry.
Standard:ANSI B16.5-1973、JPI-75-15-70、GB 699、GB1220、JB755、HG20633-9
Note:The material of the oval ring jont gasket must be 15~20HB lower than the hardness of flange,and this kind of gaskets is non-recyclable.
